(Cl. Ztl-26) 16 Claims.

This invention relates to sliding car doors and primarily to doorconstructions for preventing rain, snow, dust, cinders and the like fromentering the car.

It is an object of this invention to provide sliding doors for cars,particularly of the house type, so constructed and associated with thecar wall as to substantially exclude the entry of rain, snow, dust,cinders and the like from these cars.

A further object is to provide sliding car doors having substantiallyrigid parts and to associate said parts with substantially rigid memberson a car wall to prevent the ingress of foreign matter into the car.

A further object is to provide sliding car doors constructed andassociated with `the car wall so as to prevent damming of water, snow,dust, cinders and the like directly against the rear edge of the doors.

A further object is to provide sliding car doors, the rear portions ofwhich are constructed and associated with the car wall to present offsettransversely extending baiiies for trapping and disposing of foreignmatter exteriorly of the car.

Other objects of the invention will become clear as the descriptionthereof proceeds.

In the drawing forming part of this specification:

Fig. 1 is a fragmentary elevation of a house car and a slidingV doorthereon embodying the invention.

Fig. 2 is a horizontal section taken on line 2'-2 of Fig. 1.

Figs. 3, 4, 5, 6, 7 and 8 are horizontal sections similar to Fig. 2illustrating other embodiments of the invention.

Referring to the drawing and particularly to the embodiment of theinvention illustrated in Figs. 1 and 2, the reference numeral I0designates generally a metallic sliding door for a railway house car, aportion of the Wall of which is shown at II. The construction of therear portion of the door, the balance of the structure of which is notessential to the description of the instant invention, embodies ametallic panel I2 having horizontal corrugations one of which isillustrated at I3. The` panel is offset outwardly as indicated at I4 toprovide a flange I5 spaced laterally outwardly of the main plane of thepanel.

A relatively sturdy angular reinforcing member I6 is utilized toreinforce the rear portion of the door I0. The reinforcing member I6embodies a vertical flange I'I overlapping and secured to the flange Iof the metallic panel. 4A flange I8 extends inwardly fromr the flangeIl.' The reinforcing member IIi is then terminated rearwardly in theformof aflange I9 disposed substantially in the main plane of the panel.From the flange IS a flange 2 0 lying at substantially a right angle tothe wall II is directed inwardly across the main plane of the panel. v

A backing plate 2| extends across the space between the outwardly offsetportion I4J of the panel and the inwardlyV directed ange I8 of thereinforcing member.A This plate is secured to the panel substantially inthe main planethereof and to the rearwardly directed flange I3 of thereinforcing member. 1

Secured to the latterflangeM of the reinforcing member by means ofrivets 22 which fasten the backing plate thereto isa metallic sealingstrip 23 which is substantially Z-shaped in'section. The sealingstriphas a forwardly and `inwardly directed flange 24 spaced inwardlyfrom the backing plate 2l and adapted to cooperate with a spark strip25. The spark strip is adapted to be secured to an outwardly extendingflange 26 fastened to the door post 21. A

As appears more clearly from Fig. l of the drawing the inwardlyYdirected. flange 20 of the reinforcing member I6 is bent rearwardlyfrom its normal position so as to provide a flange 28 lying at an obtuseangle to the Wall II. The bending of the flange 2U begins at a poi-ntabove the bottom of the door so that it serves as a striking memberadapted to engage a back stop (not shown) to limit opening movement ofthe door. Where aback stop is utilized for the upper rear corner of thedoor the construction of the reinforcing member will be the same as thatabove described.

A substantially channel shapedl member 29 is secured to the post 21.This member comprises a web 35i disposed outwardly and substantiallyparallel to the Wall and oppositely extending flanges 3| and 3'2. Theseflanges extend from the web 29 toward the4 walland are disposed at anobtuse angle to the Wall. The anges 3i and 32 extending along the wallII as indicated at` 33 and 34 are fastened thereto in any desiredmanner. The extension 33 of the flange 3| is b ent to provide anoutwardly extending flange 35 disposed preferably at a right angle tothe wall.

From Fig. 2 of the drawing it will be apparent that; the angularity ofthe flanges 2,8 and 3| rela'- tive to the wall is the same, which ispreferred, and that the flange 28 lies forwardly of the flange V3-I whenthe door is closed. The described relaspect to the wall avoid damming offoreign :rnat-Y ter blown toward the rear edge of the door. foreignmatter, to the contrary, is directed outwardly so that despite thetermination of the flanges 20 and 28 short of the channel shapedV member29 very little foreign matter is blown between these flanges and thechannel shaped member. Such foreign matter as may find its Way beyondthe flanges 20 and 28 will encounter the flange 35V and be preventedfrom entering the car. The construction thus prevents damming of foreignVmatter and provides a series of transversely extending baiiles which inthe preferred construction are offset relative to each other.

In the embodiment of the invention illustrated in Fig. 3 of the drawingsan additional baffle is provided. In this embodiment the flange 20 liessubstantially at a right angle to the Wall throughout its entire height.A separate flange 35 is .secured to the'ange 20 as by means of weldingso as to lie at ancbtuse angle to thevcar Wall. The flanges 20 and 36are braced by means of plates 31 preferably welded -to the flanges. Bythis construction both the flangesV 36 and 2l! are effective as baiilesforpreventing the ingress of foreign matter into the car.

In Fig. 4 ofthe drawing the invention is illustrated applied to adifferent type of door 3B. This door comprises afmetallic panel 39formed with horizontal corrugations, Aone of lwhich is shown at 40.These corrugations merge into avertical corrugation 4| beyond which thepanel extends as indicated at 42. The vertical corrugation is bridged bymeans of a backing plate 43 which is secured preferably by means ofrivets to the panel on opposite sides of 'the-corrugation. A sealingstrip 23 is secured to the inside of the panel extension 42 and isadapted to cooperate with a `spark strip 25 as hereinabove described.

A reinforcing member 44-is disposed upon the outside of the panelextension 42 and is fastened Athereto and to the sealing strip 23preferably by :meansl of rivets. The reinforcing member 44 is preferablyformed from a structural T and is so disposed that the head flange 45serves as the attaching flange. The stem 4'5 of the T extendsinwardly'toward the car wall I l and the remaining head flange 41 isdeformed so as to lie at an obtuse angle to the wall. The stem 46 andthe head flange 41 are braced by means of plates 48 preferably welded tothese anges.

As inthe -two previously described embodiments vof the invention thebaille provided by the stem 46 lies rearwardly of the flange 35 of thechannel lshaped member 29. Moreover, the relationship :between theflanges 46 and 41 of the reinforcing member and the flanges of thechannel shaped wall member'29 is substantially the same as thepreviously described relationship between the reinforcing members andthe channel shaped memloer 29 of the first two embodiments of theinvention.

1 v In Figs. 5 and 6 of the drawing the door structures illustrated inFigs. 3 and 4 are shown asso- Such Y elated with a modified form of wallchannel shaped member for preventing the entry of foreign matter intothe car.

With particular reference to Fig. 5 of the drawing, it will be seen thatthe door post 49 differs structurally from the door post 21 and presentsa flange 5U extending toward the door opening. An angle member 5Iarranged with one of its flanges extending outwardly from thewwall isfastened to the door post 49 as by means of rivets 52 passing throughthe flange -53 of the angle member 5I and the flange 5i) of the doorpost.

y To the outwardly extending flange 54 of the angle member the poststrip 25 is secured. The metallic sheathing 55 of the car wall isfastened to the flange 50 of the door post 49 in any desired manner.

The modified wall channel shaped member 55 is secured to the Wall bywelding or riveting through its web 51. This web carries a flange 58adjacent to the door opening and a flange 59 remote from the dooropening. The latter flange, as clearly appears from the drawing, extendsoutwardly at an obtuse angle to the wall. The flange 59 is reinforced bymeans of plates 60 Welded to the web 51 and to the flange. These platesserve additionally as guide ribs for the door to prevent the flange 36of the door reinforcing member from fouling the flange 59 in the openingmovement of the door.

In the form of the invention illustrated in Fig. Y

6 of the drawing a door post 6I provided with a flange 62 extendingrearwardly from the door opening is utilized. To the latter ang'e themetallic sheathing 63 of the car wall and a post protection angle 64 arefastened as :by `means of rivets 65. The outwardly extending leg of thepost protection angle carries the post strip 25 which is preferablyriveted thereto as illustrated.

A channel shaped member 66 substantially similar to the channel shapedmember 53V is utilized with the door 38 having the T-shaped reinforcingmember 44. The web 61 of the channelshaped member 66 which is somewhatlonger than the web 51 of the channel shaped member 56 is secured to themetallic sheathing 63 in any desired manner. The web 61 carries a flange68 disposed adjacent to the door opening and a flange 69 remote from thedoor opening. The latter flange lies at an obtuse angle to the car wall.Reinforcing and guiding plates 1li similar to the plates 60 are employedin this embodiment of the invention.

It will be clear from the foregoing description of the embodiments ofthe invention illustrated in Figs. 5 and 6 ofthe drawing that theyprovide flanges which serve to baffle any foreign matter tending toenter the car around the rear edge of the door. vThe structure of theseembodiments, moreover, prevents damming of water or other foreign matterdirected toward the rear edge of the door and provides for the disposalof such matter outwardly of the door opening.

The construction illustrated in Fig. 7 of the drawing eliminates theseparate channel shaped member 29 utilized in the embodiment 'of theinvention illustrated in Fig.- 2 of the drawing. In the consideredembodiment the' door post 21 lis formed with an integral channel shapedportion 1l. The web 12 thereof is disposed outwardly of the car wall andis connected to the post by means of the obtusely arranged-flanges 13and 14. A plate member 15 is preferably utilized. This plate memberextends across the channel portion 1l and is fastened on opposite sidesthereof in any desired manner. There is thus provided a box sectionwhich affords reinforcement for the door post.

vAn additional baffle comparable to that provided by the outwardlyextending flange 35 shown in Fig. 2 of the drawing is employed in theconsidered embodiment of the invention. This baille is afforded by theoutwardly extending leg 16 of an angle member 'H secured to the doorpost 21 by riveting or welding. It will be apparent from a cursorycomparison of the structures shown in Figs. 2 and 7 of the drawing thatthe latter secures the same effective baffles as is provided in theformer.

A further modification of the invention is illustrated in Fig. 8 of thedrawing. This modification utilizes the door post 6| shown in Fig. 6. tothe rearwardly extending flange 62 of the door post a modified form ofpost projection flange 18 is fastened. This angle affords an outwardlyextending flange I9 for the securement of the post strip 25. Theremaining flange B of the post protection angle extends along the wallIl and is deformed so as to provide a channel shaped portion 8|. .Theweb 82 of this portion is offset outwardly from the wall and isconnected to the flange 8E! by the obtusely disposed flanges 83 and 84.The sheathing 63 of the car wall is disposed between the flanges 62 and8i! and is fastened by the rivets which secure these flanges together.

These rivets are utilized, moreover, to fasten an angle member B to thepost protection angle. One of the flanges 86 of this member extendsoutwardly from the wall so as to serve as a baille.

It will be apparent from the foregoing description of the modificationsillustrated in Figs. 7 and 8 of the drawing that the objects of theinstant invention are secured by these modifications.

It will be apparent that numerous changes and modifications in thedetails of the invention will be clear to those skilled in the art. Itis intended, therefore, that all such modifications and changes becomprehended within this invention which is to be limited only by thescope of the claims appended hereto.
